Question

solve the following equations and verify your answer : 3x-40=½x+35​

Answer 1

Answer:

3x - 40 = \dfrac{1}{2}

21 x + 35

Multiply both the sides by 2

➾ 6x - 80 = x + 70

Move like terms

➾ 6x - x = 70 + 80

Calculate

➾ 5x = 150

Divide both the sides by 5

➾ x = 30

∴ The value of x is 3030

Verification :-

3x - 40 = \dfrac{1}{2}

2

1

x + 35

By putting the value of x

➾ 3 × 30 - 40 = \dfrac{1}{2}

2

1

× 30 + 35

➾ 90 - 40 = 15 + 35

➾ 50 = 50

∴ LHS = RHS ✔✔
